slope = -a/b
Statement I & II are clearly insufficient when taken alone.
Combining I & II
x intercept = 2
y intercept = 3
slope = -2/3
Although the answer is correct but explanation is flawed.parallel_chase wrote:for ax+by+c=0dferm wrote:Please Help...

Stm1. the x-intercept of line K is 2 means it passes through (2,0)
Stm2. the y-intercept of line K is 3 means it passes through (0,3)
Slope of a line = (y2-y1)/(x2-x1)= -3/2 in this case.

X/a+Y/b =1
X/2+ Y/3 = 1
3x+2y=6
slope -a/b
-3/2.
